Ohio State coach Thad Matta received a helping hand from former Indiana coach Bob Knight.

After five teams in a row had shot better than 50 percent against the Buckeyes, Matta decided to seek outside counsel before a game against Indiana yesterday.

"I reached out to the master," Matta said.

He called Bob Knight, who had no qualms about helping the coach of his alma mater beat the school that fired him 11 years ago after an unparalleled run of success.

"He gave me this defensive drill," Matta said. "Our players hate it, but I think it made us play a lot better."

The second-ranked Buckeyes held Indiana to 38.5 percent shooting.

The rosters for the 2011 McDonald's All-American High School teams were announced on Thursday.

Hoosiers forward Cameron Watford is out indefinitely after having surgery Tuesday to repair a broken left hand.

The news comes less than two weeks after Maurice Creek had season-ending surgery to fix a stress fracture in his right knee.

"Our road to getting better and our path on how we're going to get there with the people we have took another hit," coach Tom Crean said. "He had surgery today on his left hand. He broke a bone in his hand, so he'll be out indefinitely."

Watford is Indiana's top scorer (17.0) and rebounder (5.8) and was sixth in the Big Ten in free throw percentage (83.5).
